Updated the format_phone_number_for_speech function to properly read phone numbers digit by digit instead of as large numbers.
Changes:
- Phone number 9095737372 now reads as "9 0 9, 5 7 3, 7 3 7 2"
- Instead of "nine hundred nine, five hundred seventy three"
- Added proper digit separation with commas for natural speech flow
- Handles both 10-digit and 11-digit (with country code) numbers
- Strips all non-numeric characters before processing
This makes the agent announcement much clearer when receiving forwarded calls.
